Producer Frank Marshall revealed to IESB that the plan is begin shooting the fourth Jason Bourne movie next summer, for release in 2010. As reported back in February, director Paul Greengrass and star Matt Damon are set to return. Marshall also confirmed that they’ll probably be creating an original story for the movie (predicting that Bourne will be headed to South America), since creator/author Robert Ludlum only wrote three books and wasn’t involved in the later books in the series:
IESB: The Bourne series, are we going to see another one?
Frank Marshall: Oh absolutely, Bourne 4…Hopefully we’re going to be shooting next summer for release in 2010.
IESB: Do you know which way the story is headed, is it going to be the next book?
FM: No actually, there was a fourth book written, but it was not by Mr. Ludlum, so we’re probably going to take our own direction, and we’re working on what that storyline is going to be right now.
Though he wouldn’t reveal any plot details, Marshall did say that the story would likely take place in South America.
